i have given you the charts given/given you the online calculators and the figures that agree with what i put . I told you to read what the original poster said they had and to stop making up in your own mind what they have and waffling away talking shyte . I am not here to educate you its...

i would go 120 to 130 but unless got them to hand its guess work depending on length of male part

two flashing lights on a 105 is a new board required 99% of the time . No the rad water cannot mix with the water coming out the shower she must be smelling the drains or something else

it all depends how long the male bit is that goes into the female socket More information required on what it is that is 110mm

Why are you speaking to yourself ? first sign of madness . I would go as far as saying you are round the pulled bend so from now on i will just give you the elbow

You should never have got in here in the first place if you cannot read basic charts and put half a dozen figures into a calculator Thank christ we never got into purge volumes now that would really have confused you.

I have never been a plumber in my life i am a time served gasman which is how i know about absolute basic pipe sizing and i have already broken down the figures for loss earlier in the thread what bit of those are you finding hard to read with your very obvious limited intellectual capacity ?

FFS stop putting what you think it is and put what the OP actually put its 2 elbows not formed bends jesushchrist

as i said use the calculators correctly two 15mm elbows and 1 metre of 15mm pipe with the actual figures from a logic plus 30 does not give you those figures are you some sort of halfwit that struggles to put in the basic information ? . please attempt to show me a breakdown of your comment...

and you need to read what the actual op put and stop going on about mitre bends which are not and never have been used on standard domestic copper installations let alone on 15mm but that hasnt sunk in has it . No they dont give the figure you are coming yup with . Try using them properly .

no 4 of us are now ;)

have you tried slightly unscrewing the bolts that hold the head to the body . if they are too tight it can cause this problem on these valves

Shame you dont know how to do them correctly or follow simple charts but hopefully this thread will help you in the future

wtf are you on about mitred bends which you say you have never seen on copper but want to bring them into the calcs . the OP has not said he has pulled bends he has said he has the standard every day elbows that are fitted day in day out every minute of the day on pipe runs . No when i size a...

read what the original poster actually put. Pure and simple your calcs were wrong

what the fek is a mitred elbow no the figures are for standard 90 degree elbows that are bought off the shelf in every shop/merchants that everyone uses I have gave you two charts to work off that do not have any lea way added for safety so stop talking shyte and accept that you are wrong by...

technically after filling the little pipe between the taps should be removed and the blanks put on . yet to see one done yet

yes but its been left in an awkward position so dont worry too much about it many people just use the one

use the proper pipe sizing calculators 1m meter of 15mm copper pipe is 0.49 its self 15MM elbow is classed as 0.4 of a metre so x 2 that is 0.8 of a meter so another 0.3947 So your calcs are well out Then possible allowance for the tee The figures of the logic plus 30 is 3.135m3 /33.733kw...

33 .7 kw gross on 1 metre 15mm with two 15mm elbows is a drop of 0.8881 before allowing for how may exit the tee which could possibly take it well over
